Can y’all pls help me, 20 points!!

Answer:

The last option

frutty [35]

Answer:

17\ \text{hours and}\ 15\text{ minutes}

Step-by-step explanation:

The function is

-4x+3y=21

Where

x = Time in hours

y = Velocity in kilometers per hour

Here y = 30 km/hr

-4x+3y=21\\\Rightarrow x=\dfrac{3y-21}{4}\\\Rightarrow x=\dfrac{3\times 30-21}{4}\\\Rightarrow x=\dfrac{69}{4}\\\Rightarrow x=17.25\ \text{hours}=17\ \text{hours and}\ 15\text{ minutes}

The particle will reach 30 km/hr after 17\ \text{hours and}\ 15\text{ minutes}.

What is the first term of an AP whose common difference is 2 and 31st term begin -88
castortr0y [4]

Answer:

a₁ = - 148

Step-by-step explanation:

The n th term of an AP is

a_{n = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given d = 2 and a₃₁ = - 88 , then

a₁ + (30 × 2) = - 88

a₁ + 60 = - 88 ( subtract 60 from both sides )

a₁ = - 148
